Another Star Trek thread that I believe deserves its own space.... Considering this is a crowd of Star Wars fans who in general do not like to accept every Star Wars-related story as canonical, (with some just accepting ANH and ESB, some just accepting the complete OT, some accepting the PT and OT, some accepting certain aspects of EU and not others, etc.), and considering that a thread discussing this flexible personal canon already exists, I thought a similar thread for Trek would be appropriate.
I never thought I would enjoy the Trek novels, especially considering how inconsistent they could be with each other and with movies/episodes that followed later. However, I lately have realized what a treasure some of them can be, and their lack of cohesiveness is really an opportunity to more easily disregard stuff you don't care for (I'm already pretty flexible in my concept of 'canonical' anyway).
At this point, partly due to ignorance, my personal canon accepts episodes and films related to TOS, TNG, plus TAS. But I'm starting to explore a different, parallel personal canon (in other words, it may conflict at points with the established canon, but in my head, I'm looking at an alternative canon without disregarding the established stuff). I'm considering all the James Blish short stories based on TOS episodes, all the Alan Dean Foster stories based on TAS episodes, all the book novelizations, and I'm starting to explore other novels with the TOS crew to flesh it out. As I've said elsewhere, I'm looking at stuff to tell more about the Enterprise under Robert April or Christopher Pike, the years between TOS and TMP, and the years between TMP and TWOK (wherein many say a second 5 year mission took place). I think I will really enjoy this.
